I would like to participate in those discussions but I have very strong feelings against Facebook. It's a bit hard for me to explain but it has to do with ethics and freedom. I don't believe such companies should have such a control on our lives. Of course, that depends how you use it but still, I don't want such a company to know all about my life. I also did the same with Whatsapp (owned by Facebook), Google and I never used any Apple product or bought anything on Amazon. I do realize that me behaving this way won't change anything but this is my way to be in line with what I believe in.
Sorry for the long annoying text, I just wanted to say that my leaving Facebook had nothing to do with the great group of people from BuzzerBeater, on the contrary, before closing my Facebook account, I used it only for the BuzzerBeater group.
